————— 2022-9-15 ————— Lentils also Did you guys write the Doris engine Zhi-yuan liu 15:33 the I thought Doris was mysql driven Lentils 15:56 Yes. Lentils 15:56 I've already written that the Doris engine is the mysql driver Lentils 15:57 The Doris engine is divided into two parts: 1. Synchronization and 2. Computing Zhi-yuan liu 16:00 @Lentil He does a lot of syncing. Lentils 16:06 I've already implemented Doris synchronization in FlinkX Lentils 16:07 I've tested that the Doris engine is computationally slow, especially for large amounts of data that can't be executed locally Zhi-yuan liu 16:07 What version of Doris are you using Lentils 16:07 doris1.1 Zhi-yuan liu 16:07 It is what respect is slower ah, am I used here still OK ah Zhi-yuan liu 16:08 Query with table or calculate what data? Lentils 16:08 For example, my current implementation of the Doris computing engine has the mysql driver at the bottom of it and if I do insert select or something like that it's slow Zhi-yuan liu 16:09 How much data? What kind of model? That should be pretty quick Zhi-yuan liu" He's actually doing all the asynchronous tasks Lentils, when Duplicate Zhi-yuan liu affliction Want to use as a mysql table? There is still no need to remove weights and precompute Zhi-yuan liu concealed @Lentil, go to the Doris website and just wechat them. Go in and ask the big guy Lentils 16:17 I give them big issues Lentils 16:18 The Doris audit log plug-in and the BUG just got back to me today Lentils 16:18 By the time you get back to me, I've already solved the problem Lentil is better I'm just doing pre-technical research and then I start breaking things up and I can't send them out Zhi-yuan liu is better It would be better if you went to the group to ask, they seem to be very busy distributing packets a while ago Zhi-yuan liu is better Most of them are answered by selectDb and Baidu Lentils" thank you Zosimer 16:23 Slower than Hive? Lentils for It's still faster than Hive. I'm still not familiar with Doris executing SQL Zhi-yuan liu for An upgraded version of Impala. My initial feeling was Zhi-yuan liu 16:27 Create AGG models for real-time calculations Zosimer 16:27 Have you tried the single form yet? Zosimer 16:28 Tried Doris more table than CK block Zhi-yuan liu" Ck's multi table itself is relatively slow Zosimer 16:29 Ck multiple tables don't work Zhi-yuan liu" Doris has a Colocation Join optimization, and it would be a lot faster to optimize if you could use that when you're building tables 扁豆 15:14 各位大佬 doris引擎写了么 刘志远 15:33 doris不是mysql驱动么 扁豆 15:56 是的 扁豆 15:56 我已经写了doris引擎 就是mysql驱动 扁豆 15:57 doris引擎分为两部分：1、同步 2、计算 刘志远 16:00 @扁豆 他同步方式还挺多的。 扁豆 16:06 这个我已经在flinkx里面实现doris同步 扁豆 16:07 我测试过doris引擎计算很慢 尤其是大数据量 在本地执行 还不能满足要求 刘志远 16:07 你用的doris是什么版本的 扁豆 16:07 doris1.1 刘志远 16:07 是什么方面比较慢呀，我这里用着还可以呀 刘志远 16:08 连表查询还是计算什么数据？ 扁豆 16:08 比如 我现在实现的doris计算引擎 底层就是mysql驱动 如果我执行insert select之类语句 是比较慢的 刘志远 16:09 多少数据量呀，用的是什么模型？应该挺快的呀 刘志远 16:10 他其实都是做的异步任务 扁豆 16:11 Duplicate 刘志远 16:12 是想当作一个mysql表去用？还是没有去重和预计算的需求么 刘志远 16:17 @扁豆 你去doris官网直接加他们微信，进去问问他们大佬吧 扁豆 16:17 我都给他们大佬提了issue 扁豆 16:18 doris审计日志插件还有BUG 今天才回复我的 扁豆 16:18 回复我的时候 我已经解决了 没有微众大佬及时 扁豆 16:19 我现在只是做前期技术预研 预研完了就开始分解任务 发不出去 刘志远 16:19 你去群里问问会好些，前阵子他们发包好像都挺忙的 刘志远 16:19 大部分都是selectDb和百度的去回答 扁豆 16:22 谢谢 Zosimer 16:23 比hive还慢？ 扁豆 16:26 比hive还是要快的 我现在还不熟悉doris执行sql机制 刘志远 16:26 impala的升级版本，我最初的感觉就是 刘志远 16:27 创建agg模型做实时运算 Zosimer 16:27 单表试过没？ Zosimer 16:28 试过doris多表比ck块 刘志远 16:29 ck的多表本身就比较慢吧 Zosimer 16:29 ck多表不行 刘志远 16:29 doris有一个Colocation Join的优化方式，如果建表的时候能用这个优化下会快很多 -- Best Regards ------ 康悦 ritakang GitHub：Ritakang0451 E-mail：rita0...@163.com
